I’m about to collect my Taycan turbo.
It comes with home charging cable for blue industrial connector at 16A.
The battery is supposed to never discharge more than 20%. For charging it is recommended to not charge more than 85% of the total capacity.
Respecting the above mentioned limits, we only need to charge 60.7 kwh. Doing this at 230 VAC and 16A will take 16.5 hours.
Any advice how to speed this up?
The PMCC unit can handle up to 9.6 kw. This mean I could increase the charging current up to 41 A.
My garage can handle 32A. Could I just made my self a cable between the mains outlet in the garage and the PMCC unit that can handle 32 A?
How much current can handle the cable between the PCMM unit and the car?
Thanks in advance for any advice.

If you use the industrial blue plug, it should mean that goes with ‘three phase’ current. With this and 16A I recharge mine approx 8kwh /hour - thus full charge overnight. Regards from Luxembourg

The person asking is in the UK and will be using 3-phase power, not our 240V single phase power in the US.

Why did you choose 30A on a 50A circuit when 40A is what the equipment can do? Just curious. My cable does get a bit warm on 40A.

Typo…I use the 40 amp setting. Sorry for any confusion. 40 amp creates slight warmth on the hardware.

I am in the US so I know the electric system is different here. What I can share is that my dealer recommended that I install a 40 amp line and I did that. With that in place, I can confirm that my Taycan Turbo charges at a rate that is consistently above 9 kWH per hour and some days reaches the full 9.6 kWH max level the Taycan can accept.

I got wiser after my car delivery I saw the back of the charging unit. It can handle maximum 32 A. I limit the charge to 30 A. Maybe not running at full capacity helps with the longevity of the charging unit. Or maybe the max 32 A already has implicit the safety factor. Since I don’t know, I play it safe by charging at 30A.

In the U.S. the National Electrical Code (NEC) requires no more than 80% load for a nominal rated piece of equipment. This means that a 50 amp breaker in a wall panel can handle no more than 40 amps. When I set this up for my 2022 Taycan 4S, I started with 40 amps for the charge to speed things up to the max. Didn't work. The 50 amp breaker blew at each attempt. After checking with others and testing, I found that 32amps for charge was the highest current I could use and be sure of a successful all-night charge. Things got warm, the breaker held, and it worked.
I am in S. Florida, so ambient temperature may be a contributing factor.
With the latest Porsche software change, be sure to set your charging current to the desired level as you begin each charge. Otherwise you may find the charger has reset to a lower current level and charging takes a much longer time.

My Charger tops out at 39 amps, and it resets to 20 amps each time I finish a charge.
I adjust the charging rate from 20 to 39 amps depending on the amount of time I have to charge.
I can generally charge over night with the 20 amp charging rate.
Otherwise, I have had no problems with the charging unit or the 4S
....the cable does get warm when charging at 39 amps, and it does not trip a breaker.... in upstate NY, it does not seem to present a problem.

Sounds like you have the new software update from Porsche. The charger may revert to the 20 amp point unless manually overridden. Seems to be a concern about the wires getting "warm" during charging. Not a problem for me up to the charger setting that causes my 50 amp breaker to trip.

Yes, the charger update came over the internet, and the 4s has the latest colorful update.
My breaker has been happy with a 39 amp draw...fingers crossed.
Yes, my charging cable will melt snow.

A word of caution in very cold weather....I began charging this afternoon when it was above freezing...now it's 7 degrees F, and the charging cable is frozen into the charging port!.. I am assuming that when things warm up, I will be able to get the cable to release. I may try a hot air tool to warm the unit.
